1ADS1015 (I2C)
2
3This device is a 12-bit A-D converter with 4 inputs.
4
5The inputs can be used single ended or in certain differential combinations.
6
7For configuration all possible combinations are mapped to 8 channels:
80: Voltage over AIN0 and AIN1.
91: Voltage over AIN0 and AIN3.
102: Voltage over AIN1 and AIN3.
113: Voltage over AIN2 and AIN3.
124: Voltage over AIN0 and GND.
135: Voltage over AIN1 and GND.
146: Voltage over AIN2 and GND.
157: Voltage over AIN3 and GND.
16
17Optional properties:
18
19 - exported-channels : exported_channels is a bitmask that specifies which
20 channels should be accessable by the user.
21
22Example:
23ads1015@49 {
24 compatible = "ti,ads1015";
25 reg = <0x49>;
26 exported-channels = <0x14>;
27};
28
29In this example only channel 2 and 4 would be accessable by the user.
